I installed openjdk-7-jre and icedtea-7-plugin to use webex in FireFox in Ubuntu 12.04 yesterday. Now I don't have to use JRE so I remove it. But the apt-get says that it will install openjdk-6-jre and a bunch of stuff like this:

$ sudo apt-get autoremove --purge openjdk-7-jre icedtea-7-plugin

I don't use JRE anymore so how could I remove JRE7 completely without to install JRE6?

I've read some explanations about nova-network and how to configure it like this one from wiki:

I'm confusing about a detail. If every traffic from the instances must go through nova controller node, then why we still need the public interface for nova-compute node? Is it necessary?

What happen when a request from outside to an instance. For example I have a controller node and a nova-compute node. In nova-compute node I run an instance with a Wordpress website. Then someone connect to the public IP of this instance. So the request go directly from router to the nova-compute node or from router to controller node then nova-compute node?

I installed nova + glance on my laptop. I ran an instance type m1.tiny with Ubuntu 10.04 image. Then I installed apache2 and run a wordpress site on this instance. Everything fine!

But when I reset my laptop (host machine) or stop the instance, then when I start it again, every package I installed is gone. The instance is "blank" like the brand new after I created by "euca-run-instance".

Is it the default config of Openstack or and error on my laptop? What should I do if I want to reuse the instance? Thank you!

I installed Dashboard following this guide: http://wiki.openstack.org/OpenStackDashboard

Everything fine, but when I run the server, I can not login with the username and password in DATABASE config in local_settings.py. Here's my config:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'dashboarddb',
        'USER': 'nova',
        'PASSWORD': 'nova',
        'HOST': 'localhost',
        'default-character-set': 'utf8'
    },
}

When I run the Dashboard server and enter username + password. It returned this error on browser: Unable to find the server at mykeystoneurl (HTTP 400)

And in the command line:

DEBUG:openstack_dashboard.settings:Running in debug mode without debug_toolbar.
DEBUG:openstack_dashboard.settings:Running in debug mode without debug_toolbar.

I also tried login as "admin" with password is "password" or "secrete" but I didn't work. What's wrong?

Thank you!

I'm trying to install OpenStack Dashboard following this guide from git: http://wiki.openstack.org/OpenStackDashboard

But when I run this command to sync database:

$ tools/with_venv.sh openstack-dashboard/manage.py syncdb

It returns that: 

File "/home/user1/horizon/.venv/local/lib/python2.7/sitepackages/django/db/backends/mysql>    /base.py", line 14, in <module>    
raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e)
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb

I installed package "python-mysqldb" several times, but it's still raised this error. When I run:

>>> import MySQLdb

in python interpreter, it's fine!

And I tried to install through easy_install, but the MySQL-python is installed:

$ sudo easy_install MySQL-python

Searching for MySQL-python

Best match: MySQL-python 1.2.3 MySQL-python 1.2.3 is already the active version in easy-install.pth

Using /usr/lib/pymodules/python2.7

Processing dependencies for MySQL-python

Finished processing dependencies for MySQL-python

Here are the content of tools/with_venv.sh

#!/bin/bash
TOOLS=`dirname $0`
VENV=$TOOLS/../.venv
source $VENV/bin/activate && $@

When I run: tools/with_venv.sh it returns nothing.

What's wrong in my case?
